Abstract (en)
A screen unlocking method of an electronic terminal is provided as follows. Recorded debug parameters used for selecting target fingerprint images in the most recent N instances are counted, to determine a most frequently used debug parameter, where N is a natural number. Current debug parameters are auto-adjusted based on the most frequently used debug parameter, to debug fingerprint images currently acquired. A target fingerprint image is selected from the fingerprint images debugged. Whether the target fingerprint image satisfies an unlocking condition is identified and a screen of the electronic terminal is unlocked when the unlocking condition is satisfied. Accordingly, an image acquiring method, an electronic terminal, and an image acquiring apparatus are also provided. Debug parameters only needs to be adjusted a small number of times to achieve the acquisition of fingerprint images, resolving the problem in the related art that acquisition of fingerprint images takes a longer time due to dozens or even hundreds of adjustments on debug parameters, thereby increasing the efficiency of fingerprint image acquisition, reducing screen unlocking time, and enabling the user to unlock the screen safely and quickly.
